4. Operation
•
Once installed and the power and water are connected, the unit requires no further
user interaction.
•
To operate open the outlet. As water begins to flow through the unit heating will
commence automatically.
•
An element on LED indicator will illuminate when water is flowing through the unit.
•
The heating performance of the heater is based on flow rates, the slower the flow
the higher the temperature uplift. The delivered temperature is the incoming water
temperature plus the temperature uplift (flow dependent).
•
A flow restrictor is supplied with this heater which, when fitted into the nozzle of a
tap will ensure a steady flow rate of 1.6 l/min is maintained. With this a temperature
uplift of 27°C is achieved.
•
The incoming water temperature can fluctuate dependent on time of year in the UK.
Winter may result in incoming temperatures below 10°C, whereas summer water
temperatures can be upwards of 15°C. It is imperative this is taken into account.
•
For example the heater could deliver 42°C water in the summer (with an incoming
water supply temperature of 15°C). The same product with the same flow rate would
only be able to deliver 37°C in winter (due to a lower incoming water temperature
of 10°C). The delivered temperature will be even lower if the incoming water supply
temperature is less than 10°C.
Before switching on power to the unit the system must be full of water and tested
for leaks.
This water heater is for low flow hand washing at a single basin only.
Instantaneous heaters only heat water as it passes through the tank. Because the
maximum power of the heater is fixed there is a limit to the rate at which hot water
can be delivered.
